Supplies slash standby power demands

Green power supplies meet California Energy Commission (CEC) regulations that require the power used in standby operation to be below a set level.Figures from the Energy Saving Trust on standby power use in the UK home are astonishing. Stereos on standby cost GBP 290 million and produce 1.6 million tonnes of CO2. VCRs and DVDs cost GBP 194 million and produce 1.06 million tonnes of CO2.

And TVs on standby cost GBP 88 million and produce 480,000 tonnes of CO2.

So in the UK alone, equipment on standby produces a total of 3.1 million tonnes of CO2 per year.

PowerPax offers a comprehensive range of green power supplies that meet California Energy Commission (CEC) regulations that require the power used in standby operation to be below a set level.

The standards apply to single-voltage external AC/DC or AC/AC power supplies, and among the specifications require a minimum efficiency and maximum standby power when unloaded.

The efficiency level is calculated based on power levels.

Maximum energy consumption in standby no-load mode must be 0.5W if the output is less than 10 and 0.75W if the output is between 10 and 250W.

The compliant green-mode power supplies offered by PowerPax include 18W plug top and desk top power supplies as well as 40, 50, 65, 90 and 150W desktop switch-mode power supplies, and all meet or exceed the requirements.

The low-standby-power PSUs are very competitively priced and cost only around 5% more than the standard range of PowerPax power supplies.

As an example, the 18W PTD18G green mode switch mode power supply range has no-load power consumption of less than 0.3W, and efficiency is 77% typical.

Dimensions are 88 x 50 x 34mm.

Minimum MTBF is 50,000h at 25C at full load.

The units have short circuit, overvoltage and overcurrent protection.

Input voltage is wide range 90 to 264V AC 47/63Hz via a 2-pin IEC320 C8 connector.
